FLUME-GATE.

To all whom it may concern.

Be it known that l, GEORGE E. KELLAR, a citizen of the United States,residing at Los Angelcs, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in Flume Gates, ofwhich the following is a specification.

This invention relates to improvements in flume gates and has particularrelation to fiume gate mechanisms which are adapted to be employed inconnection with irrigating systems and it is an object of the inventionto provide a simple and inexpensive and yet effective flume gatemechanism which is well adapted for use in connection with the cementpiping, stand pipes, fiumes and distributing conduits.

- The gate forming the subject matter or? the present invention has forits principal object the formation of a gate receiving portion and atubular conduit or tlume engaging portion, the parts being crimped orstamped together by machinery so as to produce a strong and non-leakingjoint in a simple and inexpensive manner.

It is also an object of the invention to pro vide the gate receivingportion with a flange upon which the adjacent tubular portion may becrimped, the said gate receiving portion being formed with a raised beador gate engaging portion insuring the formation of a tight joint whenthe gate is closed, in shutting 0d the flow of: water.

In the accompanying drawing forming a part of this specification; Figure1 is a perspective view of the flume gate forming the subject matter ofthe present invention. Fig. 2 is a horizontal. transverse sectional Viewthrough the flume gate taken longitudinally of the tubular portionthereof. Fig. 3 is an enlarged detail sectional view through the crimpedjoint or seam formed between the gate receiving portion and the tubularportion of the device.

The details of the invention will now be more particularly described,reference being had to the drawing in which 1 indicates the head or mainplate of the flume gate device, and 2 the tubular portion thereof. Thisgate mechanism is usually provided with a short tubular section 2 whichis adapted to be set in the cement of a stand pipe fiume, or otherconduit portion of an irrigating system.

The tubular portion designed to be set Specification of Letters Patent.

in the cement of such conduit, so that the plate 1 projects outside andis adapted to rece1 ve a gate 3 for controlling or shutting off the flowof water which would otherwise Issue from the said tube 2. The plate 1when made in accordance with the present invention is provided with aninwardly extending flange portion 4 surrounding the outlet opening madein the central portion of the said plate 1. The said flange 4 ispreferably connected with the plate 1 proper by means of a rolled orcurved portion 5 forming an outwardly projecting bead or raised edge 6,around the opening in the plate 1. The head or raised edge thus formedis adapted to be engaged by the gate 3, of ering a smooth and evenbearing entirely around the opening, for insuring the proper closing ofthe gate against the leakage of water. The edges of the gate are slippedbehind resilient rolled flanges 7 having their inner edges 8 arranged tobear upon the gate 3, adjacent to the sides or" the circular raisedportion 6, so that the resilient flanges 7 will firmly clamp the gate inposi tion under a spring pressure. The plate 1 is provided at the bottomwith a limiting flange 9 which prevents the gate from descending too farwith respect to the opening to be closed.

The flange 4 is adapted to extend into the end of the tubular part 2 andby means of suitable dies and formers, the lapped edges of the said tube2 and the said flange 4 are curved and crimped tightly upon each otheras clearly indicated at 10 in Figs. 2 and 3. The edge 2 is thus tightlysecured to the plate 1 and it is found in practice that a water tight jont can be made between the parts in this simple and efiective manner.

The crimped portions of the adjacent parts are preferably arrangedsufficiently to one side of the plate 1-, to permit of the crimping iescoming together in a proper manner. The joint thus formed between theparts is also so located that it is generally embedded in the cement ofthe flume, conduit stand-pipe or other irrigating channel so that anytendency to leak at this point would be prevented by the cement as willbe clearly understood by inspection of Fig. 2.

It will be evident that the gate is simple in structure and requires nosoldering, and can be employed at any points in an irrigating systemwhere the fiOW' of water is to be controlled from fluines, conduits andthe like.

lVhat I claim is;

1. A fluine gate, comprising a gate receiving portion having a flangeprojecting beyond one face thereof, and a tubular portion crimpedthereon.

2. A fiunie gate comp-rising an apertured plate having a flangeprojecting to one side from the edges of the aperture in said plate anda tubular portion having its edge fitting upon said flange, and crimpedtightly thereon for joining the parts.

3. A flume gate comprising a gate holding plate having a centralopening, the late being provided with a projecting rib about saidopening and a projecting flange, the said rib portion being adapted toform a water tight joint With a gate, and a tubular portion receivingthe said flange and fitting upon the same, to hold the parts togetherand form a tight joint.

4. A fiume gate comprisinga gate holding plate having side gate engagingflanges, and a central opening, the metal of the plate being shaped toform a projecting bead or ridge about the said opening and having acurved flange projecting to one side of said opening, and a tubularportion having a correspondingly curved edge fitting upon the saidcurved flange, the curvature of the parts serving to lock the sametogether.

In Witness that I claim the foregoing I have hereunto subscribed my namethis 24th day of April, 1911.
